Any spec's available for that? I'd love one.
That is a beautiful gun.
Bound to be some great self satisfaction for putting it all together!
Is there any loss of strength using a round breech block vs a squared off version

nice all around and well done !
Years ago someone posted pics of one of your rifles over at homegunsmith.com. I scaled the drawing and built 0ne in 327 federal. I am currently shooting the 150 gr cowboy bullet from rcbs, with 10 gns of reloader 7. I will find some pics in a day or so.
I'd love to see some pics of that. I have heard of guys building them, but never seen pics of any others.
I honestly have no clue about strength vs a rectangular block......I am sure it would take a huge overload to destroy either version. Usually it seems as thought the weak link is the hoop strength or barrel wall, not the action itself.

A guy named Joeyv over on weaponsguild built one in 30-30 and was what inspired me to build my own. I just got the steel I ordered and it will yield 2 receivers.
The first one will be in 30-30 with a 94 winchester barrel that I have.
The next one will be in 45-70.
I get to have shoulder surgery tomorrow and will be immobile for 4 weeks, then therapy.
Hopefully I can start it in a couple of months.
Thanks for the pics and inspiration.

I used some steel that was marked "grade 70 mild" for the receiver. It was 1 and 1/4 thick. I blued all of the parts in pure Potasium Nitrate. The receiver should have stayed in the salt bath a while longer. I agree that the hoop strength is the weak part. I turned off the threads where the barrel protruded into the breach block hole. This caused the 327 casings to swell in that area of the chamber, so I set the barrel back and left the threads. Funny how that little bit of metal made all the difference.
looks great

That's cool as heck man! Thanks for showing that.
Looks a lot like my second version, which was a bit more complicated than version 3.

she will put 5 rounds in under and 1 1/2 at 75 yards with open sights.
That's a nice looking rig and well done. I love seeing ingenuity at work.
Look twice, shoot once.
I think the round block and recess would be suitable for quite a bit more pressure than .30-30, if the material is right and the hole isn't too much interrupted at the rear. There are specialist services that will broach a round hole to square - with limitations on depth, so that you would have to mill a slot up to about the level of the bottom of the barrel, but that should be enough.
Here is another picture of my steel block with a spark eroded mortice to accept Cadet Martini internals.
Very nice rifles, Darcy! I too saw those drawings that were posted several years ago, saved them but haven't built one yet. I like this third design, agree with you on the improvements. Was brainstorming about it the last couple weeks, I think an ejector could be made fairly easily with your current extractor, just modify the actuator pin on the lever to be in a slot instead of a hole, pivot on a small pin in the bottom of the slot right close to the lever pivot pin. Put a small Spring behind and there you go! Would also need to have it engage the extractor a bit sooner so as to compress the spring so as soon as the empty case can clear the block it'll pop out.
Anyway great job!
Nice looking BUT Trapdoor or lower Marlin strength?? Decide which please or HUH?????????????????????????????????
Testing is needed IMHO by a LAB. Not being mean but what you stated is not computable. Sorry.
Look in several loading manuals......some list trapdoor up to 28000 psi, and some consider that Marlin level. Some keep the TD loads at 21000.
I personally keep my max loads about 28000 PSI. What I meant to say was, trapdoor loads are safe, and most of the starting loads for marlin are also well within what I consider prudent.
I proof tested with a load that loosened the primer pocket with one firing.....starline brass, which is good stuff. I never meant to go quite that hot, but the chamber is tight, the throat, short, and the powder was compressed quite a bit.......so I overshot my intended proof test load pressure a bit.
I am fully confident with my loads in the 28000 PSI range and consider that to include a fairly safe margin for error regarding the strength of this action.
When you build one feel free to have them tested by a lab. Personally , I'm not sure I'd trust any dog to do such testing, regardless of breed.

I must agree and in fact will go so far as to say trying to get one lab tested is quite simply nonsense, even if you could find such a place that would do this and certify the action (if they don't certify it what would even be the point?) it would cost many times what the rifle would even be worth! Like you I just loaded some test loads that were waaaaaaay over my intended max of 28,000 PSI, again the same as your max, and fired them remotely from a safe distance. No other testing is necessary and I don't see how a lab would offer any more assurance than the badly flattened primers and somewhat loosened primer pockets that resulted from my two heaviest test rounds, there were zero indications of any additional looseness in the action, no increased clearances or any other changes I could find. Besides pressure testing with controlled intentional overloads is the usual way new firearms are tested and has been since the invention of gunpowder!
